The patch ad511e260a27b8e35d273cc0ecfe5a8ff9543181 (crypto: qat - Fix incorrect uses of memzero_explicit) broke hashing because the code was in fact overwriting the qat_auth_state variable. In fact there is no reason for the variable to exist anyway since all we are using it for is to store ipad and opad. So we could simply create ipad and opad directly and avoid this whole mess.

2015-01-13crypto: qat - fix device reset flowAllan, Bruce W8-47/+128
When the device needs a reset, e.g. when an uncorrectable PCIe AER event occurs, various services/data structures need to be cleaned up, the hardware reset and the services/data structures initialized and started. The code to perform the cleanup and initialization was not performed when a device reset was done. This patch moves some of the initialization code out of the .probe entry- point into a separate function that is now called during probe as well as after the hardware has been reset. Similarly, a new function is added for first cleaning up these services/data structures prior to resetting. The new functions are adf_dev_init() and adf_dev_shutdown(), respectively, for which there are already prototypes but no actual functions just yet and are now called when the device is reset and during probe/cleanup of the driver. The down and up flows via ioctl calls has similarly been updated. In addition, there are two other bugs in the reset flow - one in the logic for determining whether to schedule a device reset upon receiving an uncorrectable AER event which prevents the reset flow from being initiated, and another with clearing the status bit indicating a device is configured (when resetting the device the configuration remains across the reset so the bit should not be cleared, otherwise, the necessary services will not be re-started in adf_dev_start() after the reset - clear the bit only when actually deleting the configuration).

2015-01-08crypto: qat - Fix incorrect uses of memzero_explicitHerbert Xu1-25/+20
memzero_explicit should only be used on stack variables that get zapped just before they go out of scope. This patch replaces all unnecessary uses of memzero_explicit with memset, removes two memzero_explicit calls altogether as the tfm context comes pre-zeroed, and adds a missing memzero_explicit of the stack variable buff in qat_alg_do_precomputes. The memzeros on ipad/opad + digest_size/auth_keylen are also removed as the entire auth_state is already zeroed on entry.

2014-12-26hwrng: core - Move hwrng_init call into set_current_rngHerbert Xu1-14/+16
We always do hwrng_init in set_current_rng. In fact, our current reference count system relies on this. So make this explicit by moving hwrng_init into set_current_rng. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2014-12-26hwrng: core - Do not register device opportunisticallyHerbert Xu1-11/+12
Currently we only register the device when a valid RNG is added. However the way it's done is buggy because we test whether there is a current RNG to determine whether we need to register. As the current RNG may be missing due to a reinitialisation error this can lead to a reregistration of the device. As the device already has to handle a NULL current RNG anyway, let's just register the device always and remove the complexity. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-12-26hwrng: core - Fix current_rng init/cleanup race yet againHerbert Xu1-3/+11

2014-12-22hwrng: use reference counts on each struct hwrng.Rusty Russell1-43/+92
current_rng holds one reference, and we bump it every time we want to do a read from it. This means we only hold the rng_mutex to grab or drop a reference, so accessing /sys/devices/virtual/misc/hw_random/rng_current doesn't block on read of /dev/hwrng. Using a kref is overkill (we're always under the rng_mutex), but a standard pattern. This also solves the problem that the hwrng_fillfn thread was accessing current_rng without a lock, which could change (eg. to NULL) underneath it.

2014-12-22hwrng: move some code out mutex_lock for avoiding underlying deadlockAmos Kong1-3/+3
In next patch, we use reference counting for each struct hwrng, changing reference count also needs to take mutex_lock. Before releasing the lock, if we try to stop a kthread that waits to take the lock to reduce the referencing count, deadlock will occur.

2014-12-22hwrng: place mutex around read functions and buffers.Rusty Russell1-3/+17
There's currently a big lock around everything, and it means that we can't query sysfs (eg /sys/devices/virtual/misc/hw_random/rng_current) while the rng is reading. This is a real problem when the rng is slow, or blocked (eg. virtio_rng with qemu's default /dev/random backend) This doesn't help (it leaves the current lock untouched), just adds a lock to protect the read function and the static buffers, in preparation for transition.

The powerclamp trainwreck will still work, it just wont get the benefit of long idle sleeps" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: tick/powerclamp: Remove tick_nohz_idle abuse

git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux Pull second batch of powerpc updates from Michael Ellerman: "The highlight is the series that reworks the idle management on powernv, which allows us to use deeper idle states on those machines. There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem. An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we take it through the powerpc tree. A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit maintainers. A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file, so that tools can use it. Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and the patch to add __force to get_user() so we can use bitwise types" * tag 'powerpc-3.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux: powerpc/powernv: Ignore smt-enabled on Power8 and later powerpc/uaccess: Allow get_user() with bitwise types powerpc/powernv: Expose OPAL firmware symbol map powernv/powerpc: Add winkle support for offline cpus powernv/cpuidle: Redesign idle states management powerpc/powernv: Enable Offline CPUs to enter deep idle states powerpc/powernv: Switch off MMU before entering nap/sleep/rvwinkle mode i2c: Driver to expose PowerNV platform i2c busses powerpc: add little endian flag to syscall_get_arch() power/perf/hv-24x7: Use kmem_cache_free() instead of kfree powerpc/perf/hv-24x7: Use per-cpu page buffer cxl: Unmap MMIO regions when detaching a context cxl: Add timeout to process element commands cxl: Change contexts_lock to a mutex to fix sleep while atomic bug powerpc: Secondary CPUs must set cpu_callin_map after setting active and online
2014-12-19Update/Remove soon-to-be-dead email addressDave Jones4-7/+5
I'm leaving Red Hat at the end of December 2014, so remove all references to my soon-to-be-dead address. (There are some references left in the tree, that need additional changes, I'll send those through the AGP maintainers).

2014-12-19macintosh: therm_pm72: delete deprecated driverWolfram Sang4-2615/+0
The new driver is around for more than 2 years now, so the old one can go. Getting rid of it helps the removal of the legacy .attach_adapter callback of the I2C subsystem. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-12-19tty: 8250_omap: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki1-7/+7
The 8250_omap serial driver is a new user of CONFIG_PM_RUNTIME. However, after commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM in 8250_omap.c. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-12-19spi: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki2-4/+4
A couple of new CONFIG_PM_RUNTIME users have been added recently in the SPI subsystem. However, after commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/spi/ (again). Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Mark Brown <broonie@kernel.org>
